In this contribution to Open! Commonist Aesthetics, Matteo Pasquinelli, referring to Alfred Sohn-Rethel and Alain Badiou, questions the master-slave relation between Capital and Number. Money can be regarded as an abstract machine like others that replaces and amplifies previous social relations. As any other machine, it can be analyzed according to its inputs and outputs, to the division of labour and social relations that it engenders. The new abstractions of science, the new technologies of computation and augmented intelligence, should be adopted within an extended definition of both money and labour, Pasquinelli asserts.
